Can Overheating CPU Cause Lag? Guide 2022

Universal law states that anything that works produces a certain amount of heat dissipation. Just take a look around. Your computers get heated after a while, your TVs, anything from your daily household items to huge machinery and what not, produces heat.

Often, the heat produced tends to slow our work down, primarily because overheating can lead to product damage and much more. The same thing happens with our CPUs. We all must have noticed that when overworked, the CPU will heat up, and most of the time, it does cause a lag in your activities.

Today, the main focus of this article is to provide you with simple and effective ways to keep that CPU temperature cooler for longer and avoid an unnecessary lag in your online and offline activities, as well as how to maintain that. So, stay tuned.

Can an overheated CPU cause lag?

The answer is yes. It can. When you are streaming videos online or offline, playing games, designing 3D designs on your gadget, and doing other forms of heavy work on your PC, you need your CPU and GPU at maximum clock speed.

Heavy loads on your computer can cause a lot of heat production. When there is a constant increase in temperature, the frames between the CPU and GPU get delayed due to frames either skipping or lagging.

There are multiple reasons why your CPU gets overheated. Here are some of the most common reasons:

  1. Simultaneous procedures and applications are running.
  2. Concurrent use of too many browser tabs.
  3. Air circulation is compromised.
  4. Blocked air vents.
  5. outdated operating system.
  6. Excessive dust builds up on PC fans and vents.
  7. Malware software.
  8. Viruses.
  9. An overclocking CPU

You can be dealing with either one or many of these problems at the same time. But don’t worry. Read this article till the end, and you can tackle this issue once and for all.

  3. Then, press the Windows key.
  4. Search for MSI Afterburner.
  5. A pop-up window will appear.
  6. Click on Settings, MSI Afterburner properties.
  7. Scroll down to the CPU temperature.
  8. Click on the Active hardware monitoring graphs.
  9. Ensure that dll or HwiNFO.dill is clicked.
  10. Then click OK.
  11. Hit “Apply” and “Okay.”
  12. Next, press the Windows key.
  13. Search HwiNFO.
  14. Open HNinFO settings.
  15. Enable features
  16. Click OK. HWiNFO window will appear to click on the sensor only. The press run
  17. Look for the HwiNFO app in your toolbar and open the app.
  18. Go to MSI Afterburner again and then press K to launch MSI Kombustor.
  19. Run the stress test button and check your CPU’s temperature.

How to Fix an Overheating CPU Issue?

It is relatively easy to overcome this issue. Cleaning your PC, replacing the thermal paste, closing applications not in use, and other steps can ensure that your PC runs at an optimal temperature.

To manually fix your overheating issue, follow these steps:

  1. Remove the components from your PC.
  2. First, clean the cooling fan and get all the dirt off.
  3. Change the thermal paste and apply a new one.
  4. Invest in an external cooling system.
  5. Sit in a cold room.
  6. Use more exhaust fans if possible.
  7. Close programs that consume a lot of power.
  8. Get a semi-or fully modular power supply unit.

Besides this, you can also fix this overheating issue by using the default motherboard BIOS settings. Here is how you can do that:

  1. Press either the Del or Esc key and then enter your BIOS settings.
